All the surface are frictionless then acceleration of the block B is 2g /n. Find n.

Answer:

Solution:

String constraint: $x_{C} = 3 x_{1} + 4 x_{2}$ , so $a_{C} = 3 a_{1} + 4 a_{2}$

Block A is pulled by three rope segments: $3 T = m a_{1}$

Block B is pulled by four rope segments: $4 T = m a_{2}$

For the hanging block C: $m g - T = m a_{C}$

Substituting: $m g - T = 25 T$ , so $T = \frac{m g}{26}$

$a_{B} = a_{2} = \frac{4 T}{m} = \frac{4 g}{26} = \frac{2 g}{13}$ , so $n = 13$
